COLUMBIA, South Carolina (CNN) - The presidential campaigns of Democratic Sen. Joseph Biden and Republican Sen. John McCain announced today that their candidates will stump in the Palmetto State next week.

Biden, who is focusing most of his resources on Iowa, will hold a meet and greet in Rock Hill in the morning, then head to Columbia for a press conference at the State House.

McCain, returning to South Carolina for the second time in two weeks, will spend three days here starting Tuesday. He'll make stops in Westminster, Camden, Orangeburg, Charleston, and Pawley's Island.

UPDATE: The Biden campaign tells CNN the senator will announce some state endorsements at his State House press conference on Monday.
